To all whom it may concern:

Be it known that I, WILLIAM H. Mo-

CONNELL, citizen of the United States, re-

siding at Richmond, in the county of Henrico and State of Virginia, have 1I1V6Ilt66l.

My invention consists in the novel features hereinafter pointed out reference being had to the accompanying drawings which illustrate one form in which I have contemplated embodying my invention and said invention is fully disclosed in the following description and claims.

Referring to the said drawings, Figure 1 represents a side elevation of an apparatus embodying my invention, the exterior casing being shown in section. Fig. 2 is a top plan view of the apparatus with the casing removed, the foot rest on the left side of the machine being also removed, together with the brushes, the driving shafts for which are shown in section. elevation of one of the complete brush carriages detached from the machine, with the brush carried thereby. Fig. l is a vertical sectional view of the same. Fig. 5 is a side elevation of one of the brush carriages with the brush removed. Fig. 6 is a diagrammatic top plan view of the curved portion at the end of one of the endless tracks, showing a carriage frame, and its guiding rollers in three diflerent positions in relation therewith. Fig. 7 is a vertical sectional view on line 77 of Fig. 6. Fig. 8 is a vertical sectional view on line 88 of Fig. 6. Fig. 9 is a diagrammatic plan view of one side of the machine showing the endless carrier for propelling the brush carriages and illustrating the carriage frames, and idler frames in section. Fig. 10 is a similar view showing the endless driving chain, and the driving sprockets carried by the several carriages in engagement therewith, the carriages being shown in section. Fig. 11 is a detail view representing one of the brush carriages as it appears when passing around the front end of the endless track, with the brush supporting device ele vated and the brush carried thereby depressed into contact with the top of the Fig. 3 is an shoe, the adjacent parts being illustrated in section. Fig. 12 is a horizontal sectional view on line 12-42 of Fig. 5. Figs. 13, 1 1 and 15 are detail views representing the blacking reservoir and cooperating parts. Fig. 16 is a transverse vertical section of the forward end portion of the upper track shown in Fig. 6. Fig. 17 is a side elevation of the upper track frame near the forward end portion, as shown in Fig. 6. Fig. 18 is a front elevation of the curved portion of the upper track frame. Figs. 19 and 20 are transverse vertical sectional views on lines 19-19 and 2020 of Fig. 2, the brush carriages and chains being removed.

In the drawings 1 represents a base plate or bed which I preferably employ and which is constructed to receive and support upon a common base all the various parts of the mechanism, the said base plate being preferably of skeleton form in order to avoid waste of metal. Upon the forward portion of the base plate 1 are arranged two parallel supporting frames 2, 2, each of which is provided with a single shoe support and with instrumentalities including a plurality of traveling brush carriagesprovided with brushes, and means for securing the desired travel of the said carriages and the desired operation of the said brushes, for the purpose of cleaning and polishing a single shoe. As the said supporting frames 2, 2 and the mechanism associated therewith are identical in construction and operation, a description of one of said frames and its associated parts will describe both.

Each of the supporting frames 2 is provided with an endless track for guiding the brush carriages during their travel around the adjacent shoe support 3. This track comprises an upper track rail which extends downwardly from the upper track frame 4 and a lower track rail which eX- tends upwardly fro-m the lower track frame 5. The lower track frame 5 is supported by suitable brackets or otherwise from the base plate-1 and at some distance above the base plate and the track frame t is supported directly above and suitably spaced from the lower track frame 5. Obviously these parts of the supporting frame may be formed integrally or may be formed separately and connected together in any suitable manner, as may be found most convenient in the construction and assembling of the machine. The upper track rail which depends from the upper track frame 4 com prises the longitudinal parallel track rails 4t and the curved track rails G at each end of and connecting said parallel track rails 4 the said curved track rails being carried by substantially semicircular extension pieces 6 forming the front and rear end portions of the upper track frame at. The lower track frame 5 is correspondingly provided with parallel longitudinal track rails 5 and curved track rails 7 extending upwardly from. the lower track frame, the curved track rails 7 a being formed on substantially semi-circular extensions 7, forming the front and rear end portions of the lower track frame.

Substantially midway between the upper and lower track frames is an endless carrier consisting in this instance of a sprocket chain, which is supported at the front end of the supporting frame by a sprocket wheel 9 on an idle shaft 10, which is mounted in suitable bearings in the extensions 6 and 7 of the track rail frame and the said carrier, which is indicated at 8, is supported at its rear end. by a sprocket wheel 11, the same being the driving sprocket, mounted on a vertical shaft 12 supported in hearings in the supporting frame about midway between the ends thereof, see Figs. 1, 2 and 9. The links of the carrier or sorocket chain 8 with which the teeth of the sprocket wheels 9 and 11 engage, are of greater width vertically than the said teeth as shown in Fig. 1 and also in Fig. 11, for a purpose hereinafter more fully explained.

Below the lower track frame 5 is an endless driving belt consisting in this instance of a sprocket chain 13 supported at the front end of the machine by a sprocket wheel 1 1 on the idle shaft 10 before referred to and at the rear end of the supporting frame 2 by a sprocket wheel 15, on a vertical shaft 16 mounted in the supporting frame concentrically with the rear curved track rails G and 7. This driving sprocket chain 13 also has the links of the same which engage the teeth of sprocket wheels 14: and 15, of greater width than the said teeth, as shown in Figs. 1 and 11, for a purpose hereinafter more fully explained.

The idle shaft 10 at the front end of the supporting frame 2, is adj ustable in a forward direction for the purpose of keeping the sprocket chains 8 and 13 at the proper tension. To this end the semi-circular extensions 6 and 7 of the upper and lower track frames are each secured to a horizontally disposed adjustable block 17 provided with lateral guiding portions 18 which have a sliding engagement with grooved portions of the parallel rail sections 4 5, as indicated in dotted lines in Fig. 2 and as more clearly shown. in Fig. 16. The upper and lower track frames are each provided with adjusting screws 19, engaging the rear faces of the blocks 17, 17 and by turning said screws the said blocks and the extensions 6 and 7 can be adjusted longitudinally of the supporting frame 2, carrying with them the shaft 10, which can thus be adjusted to the desired position to hold the sprocket chains taut.

Upon the endless track previously de' scribed, a plurality of brush carriages are placed, preferably five in number. These brush carriages are exactly the same in construction and operation, except for certain features which characterize the dauber brush carriage and which will be referred to in detail hereafter, and therefore a description of one of said brush carriages will suffice for all. Each of the brush carriages, one of which is illustrated in detail in Figs. 3, 1, 5 and 11, is provided with a carriage frame 20, shown in detail in Figs. 6, 7 and 8, and comprising a bearing sleeve 21 provided with horizontally disposed upper and lower brackets or flanges 22 and 23, the same carrying guiding projections, preferably in the form of friction rollers, which engage the upper and lower track rails, as hereinafter described, and guide the carriage in its travel around the endless track. Each of said flanges or brackets is provided with three of said guiding projections or rollers, an inner roller 21 which engages the inner face of the track and is preferably located in a central position with respect to the axis of the sleeve 21, or in other words, a line connecting the centers of said sleeve and said inner roller, will be disposed transversely to the line of travel of the carriage. Each of the brackets or flanges is also provided with two exterior rollers 25 and 26 which engage the outer face of the track rails and are disposed at substantially equal distances on opposite sides of a line connecting the centers of the roller 24- and the sleeve 21. For convenience of reference, I will refer to the roller 25, which is on the forward side of said line, as the front or leading roller and the roller 26 as the rear roller. The front and r 111' rollers are located in different horizontal planes, so that they engage different portions of the exterior face of the track rail. In the present instance the front or leading roller 25 of the upper bracket 22 is located above the horizontal plane of the rear roller 26, the said leading roller having a reduced or cut away stem portion 25 as shown in Fig. 8. The curved track portion 6 at each end of the upper track rails, is of greater thickness than the track rails et as shown in Fig. 6 and each of said track rails 1 is provided with an exterior boss 4" at each end, the exterior surface of which is concentric with the exterior surface of the curved portion 6 These bosses do not extend, however, the full width of the exterior vertical face of the track rails 4P, as shown in Figs. 6 and 17, Fig. 6 showing the form of the upper track at the front end of the machine and Fig. 17 a side view thereof,

thus on the right hand side of the upper track rail (looking toward the front of the machine from the rear thereof) the boss P is adjacent to the lower edge of the track rail 4 and forms a continuation of the adjacent port-ion 6 of the track 6. The curved track 6 is cut away, as indicated at 6 to form a straight face in line with the adjacent straight portion 4? of the rail 4* above the curved port-ions 4 6 The construction of the corresponding parts at the left hand side of the track, see Fig. 6, is the converse of this construction previously described, the boss 4: being adjacent to the upper face of the track and the curved rail 6 having the straight face 6 adjacent to its lower edge in line with the portion 4: of the track rail 4 The construction of the curved track rail 6 at the rear end of the upper track frame 4 is exactly the same as that shown in Fig. 6 and the construction of the lower track rails 5 7 is exactly the same as the construction of the upper track rails 49, 6 The lower bracket 23 of the carriage frame is provided on its lower face with three guiding projections 01' rollers 24*, 25 and 26, the roller 24 engaging the inner face of the track rail and the rollers 25 and 26 engaging the exterior face of the track rail and being located in different horizontal planes, the arrangement of the three rollers on the lower bracket 23 corresponding to that of the rollers on the bracket 22 if the latter bracket were inverted. The lower bracket is also provided with vertical rollers 23 engaging the top face of the track.

The object of the construction just described is to guide the carriage frame accurately in making the turns at the end portions of the endless tracks so as to maintain the carriage frame at all times in definite relation to the part of the track which it engages, or in other words to hold it at all times so that a line connecting the centers of the inside roller 24 and the sleeve 21, will be substantially perpendicular to the direction of travel of the carriage frame. Referring to Fig. 6, I will now describe in detail the manner in which this is accomplished with reference to the three rollers on the upper bracket 22 in passing around the curved portion 6 at the front end of the upper track, in the direction indicated by the arrow, it being understood that this description applies also to the turn at the rear end of the upper track and that the corresponding guiding actions occur on the lower track which is engaged by the guiding rollers of the lower bracket.

In Fig. 6 I have shown a carriage frame in three different positions which it occupies in making the turns. In the first or lower position, the inner roller 24 is in engagement with the inner face of the track rail P; the exterior leading roller 25 has passed above the boss 49 along the straight portion 4 of the rail P and the straight portion 6 of the cut away part of the curved rail 6*; the rear exterior roller 26, which is on a lower'plane than that of the leading roller 25, is approaching the curved boss 4. This position of the parts is also illustrated in side elevation in Fig. 17. The forward movement of the carriage in the direction of the arrow, it will be seen, will cause the leading roller 25 to pass from the straight face 6 to the outer curved face of the rail 6 at the same instant that the rear roller 26 passes from the straight outer face of the rail P to the curved outer face of the boss 4', thus maintaining the carriage frame in its proper relation to the direction of travel as well upon the curved part of the track as upon the straight, the additional thickness of the curved part 6 preventing any looseness or play which would result if the curved part of the rail were made of the same thickness as the straight rail section 45*. The right hand position in Fig. 6 shows the position occupied by the carriage frame in the central portion of the curved track rail 6 and the upper position in Fig. 6 shows the carriage frame in the position which it occupies when leaving the curved portion 6 In this latter position it will be observed that the leading roller 25 has engaged the straight outer face of the straight rail section 45, at the same instant that the rear roller 26 has engaged the straight out awayportion 6, of the curved rail 6, so that the further movement of the carriage frame will cause the rear roller 26 to pass beneath the curved portion 6 and the boss 49 on that side of the track. It will thus be seen that throughout the travel of the carriage frame from a straight portion of the track around the curved portion 6 to the other straight portion, and throughout its travel along the straight portions of the track, the carriage frame is always maintained and guided and held in a position definite with respect to the line of travel.

WVithin the bearing sleeve 21 of the carriage frame, is a rotatable sleeve 30 which preferably extends below the end of the bearing sleeve. This rota-ting sleeve is held from vertical movement in the bearing sleeve and to this end I prefer to provide the rotating sleeve 30 with an annular groove 31 which is engaged by a pin 32 extending through a hole drilled through the bearing sleeve 21 in line with said groove, as clearly shown in Figs. 3 and 4. This pin is what is termed a taper pin, being slightly tapered from one end to the other and when driven in place in the bearing sleeve holds the rotary sleeve 30 from vertical movement, but permits its rotation.

A brush supporting device is provided in connection with the carriage frame and comprises the following parts. represents a vertically movable shaft which extends through the rotary sleeve 30, but is connected to rotate therewith by a spline or fuitlxer engaging a groove or key way in the shaft. The upper end of the shaft 33 is reduced as indicated at 35, said reduced portion having a bearing in a head block 36 which is preferably provided with a bushing 37 fitted therein and surrounding the shaft. The upper end of the shaft 35 carries a miter gear 38 and the head block 36 is provided with two upwardly extending arms 39 forming a. yoke. The head block 36 is maintained at all times in a predetermined relation with the carriage frame while being permitted to move vertically with respect thereto. In the drawings I have shown the said head block provided with a guide rod 40 which extends downwardly therefrom and has a sliding engagement with a guiding aperture in the upper bracket 22 of the *arriage frame, as clearly shown in Figs. 3 and Above the head block 36 is a pivoted brush carrier which comprises a. sleeve 41 having downwardly extending arms 42 forming a yoke, said arms being pivotally connected to the arms 39 of the head block by a pivot bolt 43. A brush shaft liextends through the sleeve 41 which is preferably provided, with a bushing 4-5 for said shaft and said brush shaft el iis provided with a brush lt; detachably secured thereto by means of a nut li, said brush being composed of bristles, felt or other suitable material, as may be preferred. The lower end of the shaft all carries a miter gear 48 and an idle miter gear 49 is mounted on the pivot bolt loosely and meshes with the miter gears 38 and 4-8.

The head block 36 is provided with a lifting stud, preferably in the form of a friction. roller 50, projecting from the outer face of the head and secured in position by a screw 51, this roller beii'ig adapted to engage a suitable cam track or rail 52, provided at the front of the machine and extending around the foot rest 3 for the purpose of elevating the brush supporting device at that portion of its travel and lowering it again to its normal position after it has passed around the toe of the shoe.

53, F t, represents a tapered pin which extends through suitable apertures in the head and engages notches in the bushing 37 and screw 51 to lock the same in position.

I also provide mechanism for positively tilting the brush carrier and brush at certain parts of the travel of the brush carriage and to this end I provide the yoke of the brush carrier with a pinion 5% (in this instance a mutilated pinion) which is secured to one of the arms 42 of the yoke and engages a vertically movable rack bar having a sliding engagement with the head block 36. In this instance the head block is provided with a dovetailed groove 56 which receives the sliding bar 55 and said bar is provided with a controlling projection in the form of a friction roller 57 projecting on the inner side of the head block in position to engage a cam track 58 extending around the shoe support 3 within the outer cam track 52, and which may be extended entirely around the upper track frame. The normal position for the brush carrier is a vertical position, as indicated in full lines in Fig. 5 in which the head block is shown in its lowest position resting upon the top of the rotary driving sleeve 30 and it will be seen that any downward movement of the rack bar 55 will cause the brush carrier to tilt inwardly toward the shoe support or to the left in Fig. The cam track 58, which engages the friction roll 57 on the rack bar 55, is so constructed that as the brush carriage is moved toward the front of the machine, the friction roll 57 and rack bar will be depressed by the cam track 58 as the brush approaches the heel portion of the shoe rest, causing the brush to incline inwardly and sweep the rear portion of the heel of the shoe on. the shoe support which is to be cleaned and polished. The cam track will then raise the friction roll 57, restoring the brush carrier to a vertical position as it passes along the side of the heel portion of the shoe. The cam track 58 is provided with a depressed portion to depress the roll 57 and the rack bar at the instant that the brush comes opposite the concave port-ion of the shoe under the in step, so as to cause the brush to tilt inwardly and sweep that portion of the shoe and the brush is then returned to avertical position or nearly vertical position as it passes along the side of the foot portion. The outer roller 50 will then engage the outer cam track 52, thus raising bodily the brush supporting device toward the position indicated in dotted lines in Fig. 5 and full lines in Fig. 11. The inner cam track 58 will also be provided with a rising grade from this point to a point opposite the toe of the shoe, or toe portion of the foot support but the rise of the inner cam track 58 will not be so great as the rise of the outer cam track 52, the differential between the grades of the inner and outer cam tracks acting to depress the friction roller 57 and rack bar 55 with respect to the head block 36 and cans ing the pivoted brush support to tilt downwardly toward the toe portion of the shoe until it passes around the toe portion where the cam tracks 58 and 52 are provided with 'corresponding descending grades engaging the rollers 50 and 57, the differential between which gradually restores the brush carrier to a vertical position as the head block is moved downward to its normal position. The inner cam track 52 on the left hand side of the shoe support, is provided with depressed port-ions as heretofore de- 1 scribed with respect to the outer or right hand portion of the cam track, to act upon the friction roller 57 and tilt the brush carrier toward the shoe support as it passes the central portion of the foot and as it passes the rear part of the heel. By properly forming these cam tracks 52 and 58, it will be seen that the brush carrier is under control at all times and is positively tilted toward and from the shoe on the shoe support and positively raised and lowered as it passes around the toe portion thereof, thus enabling the brush to sweep every portion of the shoe which is to be polished. I prefer to provide both cam tracks 52 and 58 with double rails one above and one below the friction rollers 50 and 57 respectively, as clearly shown in the drawings, see particularly Figs. 1 and 11, so that the movements produced upon said head block and brush carrier, shall be positive in both directions. This construction obviates the use of springs or other yielding devices and enables the position of the brush to be positively controlled at all times when it is in contact with the surface to be polished.

In assembling the parts of the machine I prefer to employ five brush carriers on each of the supporting frames, as shown in the drawing and these are placed placed in position with the carriage frames thereof in sliding engagement as heretofore described with the upper and lower track rails of the supporting frame. I also provide means for properly spacing the brush carriages and at the same time enabling a bumping action to be transmitted to them for the purpose of moving them around the rear end, or what I call the dead portion, of the endless track, by which term I mean the portion of the track to the rear of a transverse line passing through the axis of the vertical shaft 12, see Fig. 9. This could be accomplished in many ways, but on account of the sharpness of the curved portion of the track, I prefer to place upon the track adjacent to each one of the brush carriages, an idle device which I term a bumper or bumper frame, illustrated at 60 and which consists of a metal frame or shell provided with top and bottom flanges 22 and 23 corresponding exactly to the shape of the flanges 22 and 23 of the carriage frame and provided with guiding rollers 24, 25 and 26 and supporting rollers 23 in exactly the same manner as are said carriage frames. These bumpers carry no mechanism and perform no function except to lie between adjacent brush carriages and communicate motion from one to the other, as hereinafter explained.

For the purpose of enabling the several brush carriages to be moved around the forward portion of the track, each of said carriages is provided with a tooth or lug 61 to engage the open links of the sprocket chain conveyer 8 below the plane of the teeth of the sprocket wheels 9 and 11, as shown in Fig. 11. As before described the open links of the chain 8 are of greater width than the teeth. of the sprocket wheels, thus permitting the engagement of the teeth 61 of the brush carriages as just described, and this construction enables the teeth 61 to remain in engagement with the chain while passing around the forward sprocket wheel 9 and to engage and disengage the chain adjacent to the sprocket wheel 11 without interfering with the teeth of said sprocket wheels.

The parts are so constructed and arranged that supposing the teeth 61 of two brush carriages engage the sprocket chain '8 on opposite sides of the sprocket wheel 11, the dead portion or rear portion of the track is just sufficient to accommodate the remaining brush carriages and intervening bumpers, as clearly shown in Fig. 9. This actually represents the position of the parts when the machine is at rest. When the machine is started and power is applied to the sprocket chain 8 or carrier, the first brush carriage on the right hand side will be moved along the track by the carrier, pushing its bumper ahead, passing around the front part of the supporting frame and thence rearward until its bumper strikes brush carriage No. 5, when brush carriages Nos. 5, 4, 3 and 2 will be moved around the dead portion of the track until the tooth 61 of brush carriage N0. 2 is forced into engagement with the carrier or chain 8. The brush carriage No. 2 will then be carried around in the same manner as No. 1, and so on until all of the brush carriages have been carried around the shoe support, when the machine will be stopped by hand or automatically as preferred.

Any desired arrangement of the brush carriages may be carried out, but in the present instance it will be understood that the first carriage will carry a cleaning brush, the second carriage a dauber brush and the third, fourth and fifth carriages will carry polishing brushes, which may be either of bristles or felt or other suitable material. Each of the brush carriages, except the one carrying the dauber brush has its rotating sleeve 30 provided at its lower end with a driving pinion 62, the teeth of which engage the links of driving chain 13 below the plane of the teeth of sprocket wheels 11, 15, so as not to interfere therewith, said chain being driven continuously during the operation of the machine and driving all the brushes ata high rate of speed, see Fig. 10. I do not consider it desirable to drive the dauber brush, except during the time that it is in contact with the shoe, as otherwise a waste of the blacking paste would result and I, therefore, provide he lower end of the driving sleeve of the dauber brush with a driving pinion 02 below the plane of the chain 13 and in the plane of a stationary chain 13 (or rack) secured to the supporting frame and extending around the front of the same parallel with the front portion of the chain 13. As the dauber carriage is moved around in its turn, the pinion (32 will engage the stationary chain 13' and rotate the brush sufficiently for the application of the paste or lQltLCliiDQ, which can be supplied thereto in any desired way.

In the drawings, see particularly Figs. 1, 13, 1t and 15, also Fig. 2, I have shown a c \"lindrical paste receptacle carried on an arm 71 secured to the sleeve 4-1 of the dauber brush carriage and provided with a vertical shaft 72 extending centrally therethrough. The receptacle 70 is provided on the side nearest the dauber brush, which is indicated in dotted lines in Fig. 13,-with a plurality of vertical slits 7 through which the bl aching paste may exude or be pressed and the receptacle is provided preferably with a stationary radial partition 71 adja cent to one side of these slits. In order to ')revent the blacking paste from drying up in the slits or in the receptacle when the machine is not in operation, I provide a slide for closing the slitted portion of the casing when the dauber brush is not in use, which consists in this instance of an annular casing 75 sin-rounding the receptacle 70 and capable of rotation thereon, said casing having an open portion 76 of slightly greater width than the. slitted portion of the using and which capable of being moved into registration therewith to permit the brush to sweep across the slitted portion of the casing, as indicated in Fig. 13, This casing is given a partial rotation by suitable means, so as to uncover the slitted portion of the receptacle 70 at the same time that the daubcr brush begins to operate and to close the receptacle as soon as the dauber brush. has ceased to operate. In the present instance the casing is provided with upwardly extending projections 77 and 78 on opposite sides thereof which are momentarily engaged by stationary projections 7 9 and 80 respectively, which in the present instance depend from the top of the inclosing casing 81 which incases the entire apparatus and is shown in section in Fig. l, the said projections 80 and 79 being located at proper points in the path of the dauber carriage to produce this result, as indicated in Fig. 2. I also provide means for automatically feeding the paste through the slits 73 which consists in this instance of a blade 82 secured to the central shaft 72 of the paste receptacle and adapted to be rotated within the receptacle, as shown in ejection 88 in the path of an adjustable trip 89 mounted in a bracket- 90, secured to the top of the casing 81 at a desired point, preferably a little in rear of the shoe support, as shown in F 2. This strip 89 is adjustable by means of a set screw 91, so as to actuate the arm more or less, as its projection 88 passes the same, thus slightly advancing the blade in the direction of the arrow, Fig. 13, every time the dauber carriage is made to travel around the shoe support.

The apparatus heretofore described, preferably operated by an electric motor 100, mounted on the bed plate 1, although it may be driven in other ways. In this iu stance, the motor armature is provided with a pulley 101 connected by a belt 102 with a band wheel 103 on a short countershaft 101, which has a pinion 105 on its other end engaging a gear wheel 106 on a longitudinal shaft 107 extending bet-ween the two supporting frames for driving the operated parts of both. In order to drive the two carriers or chains 8, 8, the shaft 107 is pro vided at its forward end with a bevel pinion 108, engaging a bevel pinion 109 on a vertical shaft 115, which carries a gear end a pinion 111 which meshes with two large gear wheels 112, 112, each of which is mounted upon the vertical shaft 12 of one of the supporting frames, thus transmitting power to the sprocket chains 8, 8. The shaft: 107 is also provided with a bevel gear 113, meshing with the bevel gear 111 on a vertical shaft- 115, which carries a gear wheel 116 meshing with two smaller gear wheels 117, each of which is mounted upon the shaft 16 of one of the supporting frames, thus transmitting motion to the driving chains 13, 13.

In the operation of the machine, it to be understood that the person whose shoes are to be shined, will preferably seat himself on a seat or chair 118 indicated in dotted lines in Fig. 1 and mounted on the top of the inclosing casing 81, placing both feet upon the shoe supports 3, 3, suitablev openings 81 being provided in the casing for that purpose. The apparatus is put in mot-ion by starting the motor 100 through the means of a suitable switch, which may be controlled by hand or which may be con trolled and operated by coin actuated mechanism (not shown) in any usual or desired manner.
